DELETE statement conflicted with COLUMN REFERENCE constraint 'FK__titleauth__title__060DEAE8'. The conflict occurred in database 'pubs', table 'titleauthor', column 'title_id'.
Has anyone else experienced a problem with this example? Let me know what is wrong
with it.
Thanks,
Ralph

<asp:DataGrid id="dgrdOriginalTitles" Runat="Server"></asp:DataGrid>
<h2>New Titles Table

<asp:DataGrid id="dgrdNewTitles" Runat="Server"></asp:DataGrid>
</body>

dgrdOriginalTitles.DataSource = dstPubs
to this
dgrdOriginalTitles.DataSource = dtblTitles
see if that works|||Thanks for the suggestion. I tried something else...I remarked out the following code and then it worked fine.
Thanks,

' Update Titles Table
dadTitles.Update( dstPubs, "Titles" )
